cool. why does it keep asking me to install it even though i already did?

Cool:
- Having the table of contents always in sight

Uncool:
- takes too long to get the original wiki link for sharing
- WW did not show the "This article is about X, did you mean Y?" message that I would've got in the original Wikipedia

Devs know about the issues and claim they have been fixed but they are still major issues.

There are random ads and loads of ads that are for the extension. Makes no sense and diminishes the UX almost entirely.

The layout doesn't improve anything at all, hero images look ok but the menus are horrible.

This addon is garbage.
